That's it pretty much. I'm getting spinning beach balls when I shouldn't. Tried booting w/C held down and it didn't work. Just prior to that on first boot of the day there was a long delay then I got a circle/w a line thru it where the apple should be. There is 4 gig and change in the memory slots. I did all I can do in disc utility till I can boot to another drive. I know I can use the disc and have one but still want to know how to reboot to an alt. drive. There is 599 gig of free space on the boot drive. Thanks,
